One deterministic module has affine ranking function length1 + -1 * i and consists of 5 locations. One deterministic module has affine ranking function length2 + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * sc1 + unknown-#length-unknown[sc1] and consists of 3 locations. One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] and consists of 5 locations. One nondeterministic module has affine ranking function -1 * s + unknown-#length-unknown[sc1] and consists of 11 locations. One nondeterministic module has affine ranking function -1 * s + unknown-#length-unknown[s] and consists of 3 locations. 7 modules have a trivial ranking function, the largest among these consists of 22 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 42.0s and 14 iterations.
